AL POLISHING ADEVI CE Filed July 25. 1923 2 smmmsmm l .13 f" gk. a 4* efor insuring uniform pressure against the' latter, springs are interposed between the bottoms of the holders 17 and the stones 16. Each spring is preferably of the form shown in Figures 2 and 5 embodying a pair of oppositely curved leaf spring ineinbers 18 centrally secured together as at 19 and having their separated ends respectively engaging the ends of the holder and the stone.

If the bottom roll 5 is found to be rough from one end to the other, it can be kept clean and polished entirely across the same by adjusting the screws 14 to place the same pressure on all of the stones 16 with the latf ter yieldingly engaging the surface of the I roll. vOn the other hand in case a roughness `onlyiI occurs at isolated points the desired ystones may be independently adjusted into contact with the surface of the roll under the necessary pressure, the remaining, stones being left out of contact with the roll at this time.

From the above description7 it is believed that the construction and oper-ritme` :is noli Iii' as the advantages of the present iiii'eiilimn will be readily understood and appm-Eiim' by tliose skilled in the art.

Minor changes may be made without departing from Athe spirit and scope of the iuvention as claimed.
